First Discovery is a action/plugin to EDDiscovery that voices out if the targeted system is known or not when in Galaxy Map. Relies on local systems data loaded from EDSM. This helps planning long and mid-range exploration routes when trying to find new discoveries. Install the .act file into the EDDiscovery/Data/Actions directory and enable it in EDDiscovery's Add-on Manager (Menu Add-ons -> Manage Add-Ons -> click Enable-checkbox on the First Discovery plugin).
